About this home
Step inside and experience the kind of tropical ease people envision when they think of the Keys. Thoughtfully styled with inviting colors, textures, and finishes, this top-to-bottom renovation reflects a careful selection of materials and design elements that give the home its warm, refined character. Every space feels considered—from the soft visual layers to the quality of the fixtures and finishes that enhance everyday living. The 2-bed/2-bath layout lives comfortably, encouraging you to slow down and stay awhile. Outside, 30' of dockage brings the island lifestyle into everyday life, complemented by a built-in grill area and a charming tiki hut that creates a relaxed setting for unwinding after time on the water. Set in Key Colony Beach—a walkable, bikeable island with pickleball, a 3-par golf course, and a friendly, community-oriented vibe—you're positioned within one of the Middle Keys' most desirable enclaves. A strong rental history adds meaningful value, giving you flexibility without compromise. For those seeking a Keys retreat that is charming, polished, and genuinely easy to enjoy, this home delivers a complete and compelling experience.
